Foursquare Launches Ad Platform for Small Businesses (Forbes) Monday, location-based mobile service Foursquare launched a new self-service advertising product for independent merchants who want to reach its 40 million users when they happen to be in the neighbhorhood. “This is the first at-scale global platform that lets small businesses all around the world buy on a hyperlocal level to find nearby customers,” said Steven Rosenblatt, Foursquare’s chief revenue officer.
